Traditional video slots define a fixed number of paylines — typically 9, 10, 20, 25 or 50 — on which matching symbol combinations from the leftmost reel pay out. More paylines means more chances of a hit per spin but doesn't directly affect RTP.
Many modern slots use 'ways to win' instead — typically 243 or 1,024 — where any combination of matching symbols on adjacent reels pays. Megaways slots take this further with up to 117,649 dynamic ways to win per spin.
Cluster pays slots eliminate paylines entirely, paying when a minimum cluster of touching symbols appears anywhere on the grid.
Example usage
- 20 paylines (Starburst-style classic)
- 243 ways (NetEnt Twin Spin)
